Description
A generic project box for ESP-12F modules which I use for temperature sensing and IR blasting.
The SCAD design allows for several variations.
Powering from an internal mini AC power brick or USB powered with 5 to 3.3V converter
Options for DS18B20 temperature sensor connection and IR blaster.
A separate SCAD has DS18B20 cable parts.
For USB powering I use a micro USB connector with easy solder connections combined with a mini adjustable down converter to give 3.3V.
For mains powering I use HLK-PM03 modules which are about the smallest one can get. I connect with a solderable 500mA slow blow fuse and secure the cable on the inside of the housing with a tie wrap.
The temp sensor connector I use is a 3 pin IC socket connector. The hole is a fairly tight fit but I add a little bit of resin glue to secure it.
I make a little board for the LED blaster which has a MOSFET driver (I use a AO3400) so that the logic from the ESP8266 can switch on to give a good current (80mA) through the LED.
The DS18B20 cable parts allow the sensor to be a bit remote and avoid any local warming.
